常见错误

❌ 错误:I need a ruler for cut the paper.
✓ 正确:I need a ruler to cut the paper.

错误在于误用介词 for 表示目的,正确应用不定式 to 表示用途(如 to cut),因为 ruler 是工具,for 通常接名词或动名词表示用途,但这里动词 cut 需用 to 引导目的状语。

❌ 错误:He is a ruler of company.
✓ 正确:He is the ruler of the company.

错误在于缺少冠词 the,正确应加 the 表示特指某个公司的统治者,因为 ruler 作为统治者义时,常与 the 连用指特定个体或职位,类似 the king 或 the boss。

近义词辨析

leader

leader 泛指领导者,强调引导或影响他人,可用于各种场合(如团队、国家),而 ruler 更具体指拥有正式统治权的人,常带权威或控制意味,多用于政治或历史语境。

She is a great leader in the community (强调引导作用),but the ruler of the kingdom has absolute power (强调统治权威)。

scale

scale 作为工具指刻度尺或比例尺,用于测量比例或尺寸,常涉及数值或地图,而 ruler 作为工具指直尺或划线板,主要用于画直线或测量长度,更简单直接。

Use a ruler to draw a straight line (简单测量),but refer to the scale on the map for distances (比例测量)。
